Use the Unified Namespace (UNS) as a graph?

🤔 I thought about if it could make sense to connect to a MQTT broker and write the topic-path in a structured and connected way to a graph database. It could reflect a companies UNS with ISA structure in a graph with query possibilities.

🤝 The UNS could be enriched by adding additional meta information to the database and be linked to the MQTT nodes. Graph queries could be used to combine the enriched data with the current values of the machines…

👉 I reactivated the Neo4J Logger in the Automation-Gateway.com, and enabled MQTT for it. It creates the nodes in a neo4j graph database based on the incoming MQTT messages.

Also interesting to explore the graph of the test.mosquitto.org hashtag#MQTT broker…

saw some go-eChargers, some solax inverters, some json scada demos (never heard about it before), and also a “Atomkraftwerk1234567890” 😀
